Answer: 19200 years
Step-by-step explanation:
The fossil in the above question has aged for 3.3 half lives. Since the half life of a fossil is given as 5730 years, the age of the fossil will be given as:
= 5730 years × 3.3333333
= 19200 years
Therefore, the age of the fossil is 19200 years.
Answer:
Lol I hope she didn't hit you yet. The answer is x=14 :)
Step-by-step explanation:
So the first thing that you would want to do is find what 9 is multiplied by to get 21. To do this, we can just do a simple algebraic equation: 9x=21. The answer is 7/3 because mAgIc. So now, we can also multiply 6 by 7/3. this would be 42/3 because of more MaGiC. 42/3 divides into 14 because im just obviously a mage. lol I hope this helped.
Answer: the probability that we observe 4 cracks when inspecting a 3 m2 section is 0.034
Step-by-step explanation:
The formula for poisson distribution is expressed as
P(x = r) = (e^- µ × µ^r)/r!
Where
µ represents the mean of the theoretical distribution.
r = x represents the number of successes of the event(cracks).
From the information given,
µ = 3 cracks per 1 m² section
It means that for a 3 m² section of the aircraft, the average number of cracks would be 9
the probability that we observe 4 cracks when inspecting a 3 m2 section would be
P(x = 4) = (e^- 9 × 9^4)/4!
P(x = 4) = 0.034
A rule of thumb in these type of equations (at least, for me, personally) is to bracket off the like term. We’ve got 3 things here, so we gotta bracket them.
(5)+(10s-8s)
So now, we’ve got them separated. Next, we perform our given function. In this case, we subtract 8 from 10, leaving us with 2.
(5)+(2s)
As we no longer have any like terms, to be simplified or otherwise, we open the brackets:
5+2s
And you’ve obtained your answer!
Answer= 5+2s
It was decreased by 20% which is $30.00 less
Making it $120.00
